It’s nice to see Ted Laturnus acknowledge there’s ways of getting around that don’t involve the automobile ["New-school cruisers are truly rider-friendly", January 29–February 5], but he has some factual errors that cannot go unremarked.
First, the physics. Fat tires and lightweight frames are not your friend when it comes to momentum. In fact, heavier frames possess more inertia once in motion. As to the tires, if fat really did roll farther, why do competitive road cyclists utilize the narrowest tires feasible? The reality is, a wide tire’s rolling resistance negates the inertial advantage of its weight, due to the larger "contact area" between rubber and pavement.
